Researchers at the Massachusetts Institute of Technology (MIT) have come up with an inexpensive technique for enlarging brain samples and studying them more closely. This new technique makes use of commonly available chemicals to help experts increase the size of tissue samples effortlessly and thus provide high resolution images. Called ‘Expansion Microscopy,’ the technique makes use of the same technology that makes the diapers extremely absorbent.

Getting newer, more powerful microscopes might seem to be the most common-sensical retort when confronted with the problem of getting images with better resolutions, but it can also be the most expensive one, which is why researchers at the MIT were looking for ways of enhancing the image resolution...
